A transformation achieving the optimal symmetric N-->M cloning of coherent states is presented. Its implementation requires only a phase-insensitive linear amplifier and a network of beam splitters. An experimental demonstration of this continuous-variable cloner should therefore be in the scope of current technology. The link between optimal quantum… (More)

The impossibility of perfectly copying ͑or cloning͒ an unknown quantum state is one of the basic rules governing the physics of quantum systems. The processes that perform the optimal approximate cloning have been found in many cases. These " quantum cloning machines " are important tools for studying a wide variety of tasks, e.g., state estimation and… (More)

A study of the thermal properties of two-dimensional topological lattice models is presented. This work is relevant to assess the usefulness of these systems as a quantum memory. For our purposes, we use the topo-logical mutual information Itopo as a " topological order parameter ". For Abelian models, we show how Itopo depends on the thermal topological… (More)
